What is katana sori
Katana sori (反り) refers to the curve of a katana blade. It is a crucial aspect of the sword's architecture that influences its handling.
The katana, historically wielded by Japanese samurai, is a single-edged sword known for its distinctive curved profile. Its unique form is achieved by employing two varieties of steel during its construction. A harder steel constitutes the blade's edge, and a softer steel forms the spine, resulting in a weapon that boasts exceptional strength and durability.
During the creation of a katana, its characteristic curve takes form when the swordsmith manipulates the blade over a charcoal fire during the forging process. The extent of the curve can vary, thereby influencing the katana's effectiveness. A more prominent curve enhances its slashing capabilities, while a subtler curve offers more flexibility for both cutting and thrusting actions.
Therefore, understanding the concept of katana sori is fundamental when selecting a katana as it significantly affects the performance of the sword. The curvature of the blade, or the katana sori, significantly contributes to the unique attributes that define this historic weapon.

- The term "katana sori" pertains to the curvature of a katana blade.
- The unique form of the katana is achieved by combining two types of steel: harder steel for the blade's edge and softer steel for the spine.
- The degree of the katana's curve influences its effectiveness. A more exaggerated curve enhances the katana's slashing potential, while a gentler curve provides more versatility for both cutting and thrusting maneuvers.
How to measure katana sori
You can easily measure the sori by calculating the nagasa, then drawing a line perpendicular to the nagasa and adding it up. The addition of the nagasa + the imaginary perpendicular line gives you the katana sori.
NAGASA (1) + perpendicular line (2) = SORI
